Performance characteristics:

High precision angular contact ball bearings (standard series)

 

718 series; 719 series; 70 series; 72 series

 

1.Structural features: ISO-based LYZYC precision bearing foundation series; ferrule material adopts high purity (electroslag remelting) bearing steel, with special heat treatment process, cold treatment process and material modification technology, which makes the fatigue life of this series of bearings substantial improvement.

2. Contact angle: 15o and 25o, can be used in pairs to withstand axial load and radial load or synthetic load.

3.Cage: The outer ring-guided phenolic resin bakelite cage and the rolling element-guided nylon cage can be selected according to different applications.

                Medium and high speed working conditions are recommended to use bakelite cage; 500000 ≤ DmN ≤ 1000000

                Nylon cages or bakelite cages are available for low to medium speed conditions.

4.Speed factor: The outer ring guides the phenolic resin cloth bakelite cage as the standard;

5. Grease lubrication DmN≤1000000 ie limit speed N≤1000000/Dm Dm—bearing medium diameter oil (minimum amount) lubrication DmN≤1500000

6.Scope of application: This type of bearing has a wide range of applications; it is mainly used for medium and high speeds requiring precise axial positioning and radial positioning, high-precision rotation and other working conditions. For example: CNC lathe spindle, all kinds of grinding machine workpiece shaft, grinding wheel spindle, photovoltaic slicer, vacuum pump, fan, precision transmission machinery.
